                          Device Owner Attribute
                 draft-turner-deviceowner-attribute-03.txt


Abstract

   This document defines the Device Owner attribute.  It indicates the
   entity (e.g., company, organization, department, agency) that owns
   the device.  This attribute may be included in public key
   certificates and attribute certificates.

Status of this Memo

   This Internet-Draft is submitted to IETF in full conformance with the
   provisions of BCP 78 and BCP 79.

   (http://trustee.ietf.org/license-info) in effect on the date of
   publication of this document. Please review these documents
   carefully, as they describe your rights and restrictions with respect
   to this document. Code Components extracted from this document must

1. Introduction

   This document specifies the Device Owner attribute.  It indicates the
   entity (e.g., company, organization, department, agency) that owns
   the device.  This attribute is intended to be used in public key
   certificates [RFC5280] and attribute certificates [RFC5755].

   This attribute may be used in automated authorization decisions. For
   example, when two peers are deciding whether to communicate each
   could check that the device owner present in the other device's
   certificate is on an "approved" list.  This check is performed in
   addition to certification path validation [RFC5280].  The mechanism
   for managing the "approved" list is beyond the scope of this
   document.

   NOTE: This document does not provide an equivalent LDAP schema
   specification as this attribute is targeted at public key
   certificates [RFC5280] and attribute certificates [RFC5755].
   Definition of an equivalent LDAP schema is left to a future
   specification.

1.1. Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

1.2. ASN.1 Syntax Notation

   The attribute is defined using ASN.1 [X.680] through [X.683].

2. Device Owner

   The Device Owner attribute indicates the entity (e.g., company,
   organization, department, agency) that owns the Device with which
   this attribute is associated.  Device Owner is an object identifier.

Internet-Draft          Device Owner Attribute            February 2010


   The following object identifier identifies the Device Owner
   attribute:

     id-deviceOwner OBJECT IDENTIFIER ::= {
       joint-iso-ccitt(2) country(16) us(840) organization(1) gov(101)
       dod(2) infosec(1) attributes(5) 69
     }

   The ASN.1 syntax for the Device Owner attribute is as follows:

     at-deviceOwner ATTRIBUTE ::= {
       TYPE                    OBJECT IDENTIFIER
       EQUALITY MATCHING RULE  objectIdentifierMatch
       IDENTIFIED BY           id-deviceOwner
     }

   There MUST only be one value of Device Owner associated with a
   device.  Distinct owners MUST be represented in separate
   certificates.

3. Security Considerations

   If this attribute is used as part of an authorization process, the
   procedures employed by the entity that assigns each value must ensure
   that the correct value is applied.  Including this attribute in a
   public key certificate or attribute certificate ensures the value for
   the device owner is integrity protected.

4. IANA Considerations

   None: All identifiers are already registered.  Please remove this
   section prior to publication as an RFC.
